Silicone Moulds

Here is a selection of silicone mould experiments, top left is from a hand cut wooden tetrahedron, bottom left is obviously a shell (I filled it in with polyfila to prevent the silicone going inside) and right is some small model parts. Finding the appropriate containers is important as the tetrahedron could have been done with a lot less silicone, the shell could have been placed on a raised platform to get a thicker set all around (top is very thin) and the small plastic parts were not properly sealed and leaked..........Learning curve!
